BRIEF DESCRIPTION OF THE DRAWINGS

The invention will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawingswherein:

FIG. 1 is a schematic perspective view of a new solid fuel turbine drive system according to the present invention.

DESCRIPTION OF THE PREFERRED EMBODIMENT

With reference now to the drawings, and in particular to FIG. 1 thereof, a new solid fuel turbine drive system embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.

As best illustrated in FIG. 1 the solid fuel turbine drive system 10 generally comprises an housing 20, a combustion tunnel 30, a turbine assembly 40, a water bath particulate collection tank 50, and at least one solid fuel cell 70

The housing 20 consists of four side walls, a roof 24, and a or 25. The housing 20 includes a first aperture 23, which extends through a first one 21 of the side walls.

The combustion tunnel 30 has a first end 31 and a second end 32. The first end 31 extends into the housing 20 through the first aperture 23.

The turbine assembly 40 is substantially aligned with the combustion tunnel first end 31 such that gases expelled from the first end 31 will turn the turbine assembly 40.

The solid fuel cell 70 is positionable within the second end 32 of the combustion tunnel 30 such that detonation of the solid fuel cell 70 forces gasses out of the first end 31 of the combustion tunnel 30.

The water bath particulate collection tank 50 is coupled to a bottom of the housing 20. The floor 25 of the housing 20 has an opening 26. The water bath particulate collection tank 50 is in environmental communication with an interior of thehousing 20.

An exhaust stack 60 is in environmental communication with the water bath particulate collection tank 50 such that excess gasses from the solid fuel turbine drive system 10 are expelled through the exhaust stack 60.

An exhaust fan 62 is positioned within an interior of the exhaust stack 60 for urging the excess gases out of the solid fuel turbine drive system 10.

The turbine assembly 40 further comprises a shaft member 42 and a plurality of fan blades 44. The shaft member 42 is positioned at the focus of the turbine assembly 40 and extends through a second aperture in a second one 22 of the side walls. The plurality of fan blades 44 each have a first end 45 coupled to the shaft member 42 and a second end 46, which extends radially outward from the shaft member 42. Each one of the plurality of fan blades 44 is used for translating a linear force fromthe gases expelled from the first end 31 of the combustion tunnel 30 into rotational energy.

Each one of the plurality of fan blades 44 is curved to maximize the capture of expelled gases and the translation from a linear force to a rotational force such that the shaft member 42 is capable of turnings a shaft for an electric generator.

The solid fuel cell 70 further comprises: a combustion mixture for generating cases used to rotate the turbine assembly 40 and a binding mixture for holding the combustion mixture in a predetermined shaped without the use of a casing.

In an embodiment the combustion mixture comprises coal dust, nitrate, and sulfur.

In a further embodiment the binding mixture essentially comprises sugar.

In still a further embodiment the combustion tunnel 30 is designed for rapid reloading of the solid fuel cells 70 for near continuous operation optimizing the solid fuel turbine drive system 10 for a substantially constant speed of rotation ofthe turbine assembly 40.

In use, the combustion tunnel is loaded with a solid fuel cell. The solid fuel cell is detonated and gasses are expelled from the first end of the combustion tunnel. The gasses strike the blades of the turbine assembly and cause the turbineassembly to rotate. Thus the shaft of the turbine assembly rotates. The particulate matter from the detonation of the solid fuel cell settles in the water bath particulate collection tank to be collected and disposed of in an environmentally friendlymanner. The excess (gasses are then expelled out of the solid fuel turbine drive system through the exhaust stack assembly aided by the exhaust fan.

As to a further discussion of the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.

With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use,are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.

Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to theexact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
